The National Instruments PCI-6512 Digital I/O Device (Part Number: 778968-01) is engineered to optimize performance in electrically noisy environments. Its programmable input filters effectively eliminate glitches, noise, and transient spikes on inputs, which are particularly beneficial for debouncing computerized switches and relays. The flexibility of channel timing settings enables users to configure the input filters for each digital line, ensuring accurate readings in demanding mechanical conditions.

The PCI-6512 operates seamlessly with NI-DAQmx driver software, available for download at ni.com/downloads, providing users with advanced features including automated code generation to streamline design and programming. This device leverages multithreaded streaming technology to enhance I/O performance and usability.

Equipped with a 100-pin high-density SCSI connector, the PCI-6512 can be interfaced with 100-pin ribbon cables or shielded cables. For cost-effective, unshielded connections, the R1005050 ribbon cable can be utilized alongside two CB-50LP or CB-50 connector blocks (CB-100 package). For shielded connectivity, the SH100-100-F shielded digital I/O cable can be used with the SCB-100 connector block. Additionally, the device features a 37-pin D-Sub connector which can accommodate 37-pin cables like the SH37F-37M shielded digital I/O cable in conjunction with the CB-37FH DIN-rail-mountable connector block.

Key specifications include 64 source output lines, a maximum input voltage of ±30 VDC, a maximum input current of 12.5 mA per line, and a propagation delay of 75 μs. The PCI-6512 requires a power supply of +4.3 to +6.3 VDC at 20 mA per port. The dimensions of the device are 5.54 inches by 4.47 inches, and it weighs 2.5 ounces. A warranty of 2-3 years is provided, and user and maintenance manuals are available for download. For pricing, please contact a sales representative for a quote.
